you gotta read books eventually. You gotta start with smaller books. Marxists.org has a lot of letters and pamphlets written by important thinkers, I started reading them when I was in high school and that allowed me to start branching out to longer texts. Personally recommend Lenin’s Working Class and Bourgeious Democracy, Marx’s Wage Labor and Capital, also Value Price and Profit is good.
im fine with pamphlets and shorter text usually, with bigger books i constantly catch myself skimming through them or losing my train of thought
